Engineering & Design

Our engineering group designs and generates CAD drawings for the machine guards and safety control systems.

MPSA offers custom-engineered machine guarding solutions to remedy the safety deficiencies identified by the on-site safety survey or risk assessment. The engineering portion of the project occurs in two phases: Preliminary Engineering and Final Engineering. Below is an outline of the activities relating to these two phases.

Phase 1: Preliminary Engineering

MPSA will begin Phase 1 by formally designating a project team that will include, among others, the safety specialist who conducted the initial safety survey, a project manager, and a controls engineer. After we gather and analyze your information, we will generate the Phase 1 Engineering Package.

We’ll visit your site to gather key information, including: 

  • Field sketches of the physical guarding solution
  • Critical dimensions of equipment to be guarded
  • Exact locations of hazards/nip points
  • Machine stop-time test results for various operational conditions
  • Minimum safe-distance calculations to determine location of physical guarding or presence-sensing devices
  • Verification that customer-provided electrical schematics match actual findings reviewed in machine electrical enclosures
  • Identification of all operator and maintenance tasks which may affect the controls architecture
  • Machine E-stop and controlled stop conditions
  • A basic safety system flow diagram to show the specific purposes of various devices

The Phase 1 Engineering Package:

Project Estimate Sheet and Bill of Materials (BOM)

This documentation covers all known aspects of the project.

Mechanical Design Package

Includes a plan view, elevation views and specified section views showing the customer’s equipment and MPSA’s proposed solution.

Safety System Electrical Findings & Controls Scope Statement

This explains aspects of the existing controls found on the equipment and the MPSA proposed controls solution scope.

Following the delivery of the Phase 1 Engineering Package, members of the MPSA project team will collaborate with your stakeholders and discuss any required changes. After these discussions, MPSA will acquire final design confirmation and provide a quote for scope change orders. By the end of this step, we will reach a fixed price for your solution(s) and obtain final approval and your purchase order. Phase 2 Engineering then begins.

Phase 2: Final Engineering

During Phase 2 Engineering, MPSA applies any changes made to the Phase 1 Engineering Package. If presence sensing devices are part of the solution, stop-time measurement will be performed. By the end of this phase, you will receive your Phase 2 Engineering Package, now ready to be released to production.

Stop Time Measurement

We use a computer-based anaylzer to accurately measure and record the stop time of your machine. This determines the proper distance to locate a presence sensing device from the hazard point and is crtical for meeting applicable safety standards.

Finalized Project Outline and Bill of Materials

This documentation covers all aspects of the project.

Finalized Mechanical Design Package

Includes a plan view, elevation views and specified section views showing the customer’s equipment and MPSA’s proposed solution.

Finalized Safety System Electrical Findings & Controls Scope Statement

Finalized design documents of MPSA’s proposed controls solution scope.

Once this package is approved, the Mechanical & Electrical Design Package shall be released to MPSA’s production teams.

Provide a compliant and safe working environment.

Take the first step. Ask MPSA to identify your machine safety and compliance issues. We can do the rest.
